By the way, in recent years, in food factories, flour mills, and warehouses that handle grain powder such as wheat flour, damage caused by pests that damage stored grains, so-called stored grain pests, has become serious. When stored grain pests occur in food factories, soot treatment and insecticide spraying are performed to eliminate them. In such a case, the food production is interrupted, and the product is removed over a certain period of time, which leads to a decrease in food production efficiency. In addition, the food production line needs to be cured in order to prevent the insecticidal component from being mixed into the food production line. Furthermore, even if the removal is completed, it is necessary to clean the cured portion of the food production line. It has been desired to shorten the time required to control these pests and save labor.

Moreover, generally, adults of stored-grain pests lay eggs in a place where grain powder is deposited, that is, in a powder reservoir. The hatched stored pest larvae feed on the flour grains and grow inside the flour pool. In order to prevent such growth, it is conceivable to frequently clean the food factory to eliminate the accumulation of powder. However, there are portions where it is difficult to frequently clean the dust pool, such as high places in food factories, and these are sources of stored grain pests.

The conventional techniques such as the above-described smoke treatment and insecticide spraying are not sufficiently effective against larvae growing inside such a powder reservoir, and are not practical.

Against this background, there is a strong demand for a method for controlling stored pests that is sufficiently effective against stored pests inside the powder reservoir and that can be easily handled even in places where cleaning is difficult.

One aspect of the present invention has been made in view of the above-mentioned problems, and the object thereof is to provide an insecticidal effect against stored larvae of stored grain pests inside a powder reservoir, which has been difficult to control by conventional techniques, and The object is to realize a three-dimensional insect repellent sheet that can easily remove pests even in places where cleaning is difficult.

In order to solve the above problems, a three-dimensional insect repellent sheet according to one aspect of the present invention contains an insect growth control agent on at least a surface, and has a three-dimensional surface constituting a concavo-convex structure, and the surface has the concavo-convex structure. It is characterized by being included in at least a part of the structure.

Insect control rate (%) = (number of adult emergence in untreated group−number of adult emergence in drug group) / number of adult emergence in untreated group Table 2 shows the results of the efficacy test. In addition, the insecticidal rate of 80-100% is A, 50-79% is B, and less than 50% is C.

(Efficacy test method 3)
The three-dimensional insect repellent sheet 1-2 and the plane insect repellent sheet A-2 were cut into a circle having a diameter of 8.5 cm, and each was placed on the bottom of another glass container (9 cm in diameter and 10 cm in height). Thereafter, 30 grams of experimental animal feed (product name: MF powder, manufactured by Oriental Yeast Co., Ltd.) was added on each sheet in the glass container. Thereafter, 15 adult adult insects were released into the glass container and allowed to stand at 25 ° C. As a control sample, a container with filter paper not coated with pyriproxyfen was also prepared. Similarly to the above, 30 grams of experimental animal feed was added to the filter paper, and 15 adult insects were released. It was left to stand under the condition of ° C. The introduced adults were removed from the container after 7 days. Then, the glass container was left still under 25 degreeC conditions, and the number of adults which emerged in the container was counted 14 weeks after removing an adult. The insect repellent rate was calculated using the number of adult emergence in the container in which the three-dimensional insect repellent sheet 1-2 or the flat insect repellent sheet A-2 was installed, and the number of adult emergence in the non-drug group.

The insect repellent rate was calculated by the following formula. The test group treated with pyriproxyfen was defined as a drug group, and the test group not treated with pyriproxyfen was defined as an untreated group.
Insect repellent rate (%) = (number of adult emergence in untreated group−number of adult emergence in drug group) / number of adult emergence in untreated group Table 3 shows the results of the efficacy test. In addition, the insecticidal rate of 80-100% is A, 50-79% is B, and less than 50% is C.

(Efficacy test method 4)
The three-dimensional insect repellent sheet 1-3 and the flat insect repellent sheet A-3 were cut into a circular shape having a diameter of 8.5 cm, and each was laid on the bottom of another glass container (9 cm in diameter and 10 cm in height). Thereafter, 30 grams of experimental animal feed (product name: MF powder, manufactured by Oriental Yeast Co., Ltd.) was added on each sheet in the glass container. Thereafter, 15 adult adult insects were released into the glass container and allowed to stand at 25 ° C. As a control sample, a container with filter paper not coated with pyriproxyfen was also prepared. Similarly to the above, 30 grams of experimental animal feed was added to the filter paper, and 15 adult insects were released. It was left to stand under the condition of ° C. The introduced adults were removed from the container after 7 days. Then, the glass container was left still under 25 degreeC conditions, and the number of adults which emerged in the container was counted 15 weeks after removing an adult. The insect repellent rate was calculated using the number of adult emergence in the container in which the three-dimensional insect repellent sheet 1-3 or the flat insect repellent sheet A-3 was installed, and the number of adult emergence in the non-chemical area.

The insect repellent rate was calculated by the following formula. The test group treated with pyriproxyfen was defined as a drug group, and the test group not treated with pyriproxyfen was defined as an untreated group.
Insect control rate (%) = (number of emergence of adults in untreated group−number of adults of emergence in drug group) / number of adults in emergence of untreated group Table 4 shows the results of the efficacy test. In addition, the insecticidal rate of 80-100% is A, 50-79% is B, and less than 50% is C.
